Hi,

Is there a method to solve the system of absolute value linear equations:
|AX|=b
x belongs to {a,b}

This is a nonlinear method of solving a linear underlying equation
so is there a method of solving the minimum norm
min || |Ax|-b ||2 ,
x belongs to {a,b} ??

I have tried a multiple tweaks for iterative solvers but couldn't find a way
